Thanks for the pointer. That was indeed the problem. There was no
kernel-devicetree in my deploy/ipk folder.
But now it works :) I actually did two things, I moved from using .ipk
to .rpm and changed to using a bare danny 8.0.
I do not know which of these fixed it. Before that I also tried to
nuke the tmp dir but that was fruitless :(
